Occasionally, I will get these vertical lines going down my screen and some flicker. I’ve had this problem with a thunderbolt to DisplayPort cable and an HDMI to HDMI cable. I also highly doubt it’s a monitor problem because it’s been working flawlessly in Linux and before that Windows.

Has anyone else experienced this? I also saw that Sequoia 15.1 released, not sure if this is a problem that Apple knows about that’s fixed in the new version. Really hoping it’s not a hardware issue with my unit.

Edit: it seems to be a monitor issue? I switched my second, identical display to be my first and didn't see the issue after a couple hours of usage. But now I've started using that first monitor again as my second monitor and it hasn't had any corruption issues yet.

I have an M3 Max that does this, but only when I plug in two monitors at once over Thunderbolt. It doesn’t always happen either, haven’t figured out exactly what is causing it. I know my M1 is only capable of a single external monitor, so part of my suspects their multi monitor support is just poorly implemented over the latest TB spec.

Using M1 with a thunderbolt dock doesn’t do it, so I know it’s not the monitor. Plus switching out one monitor for another doesn’t fix it.

In the past to debug this problem I’ve used BetterDisplay

Don’t want to send up a flare unnecessarily, but I used to see that patterning on machines with dead logic boards.

My last 17” MBP did that shortly before the board died completely & left me s.o.l. If you’re still under warranty or AC, maybe worth getting it checked?

I am not certain if this would be an issue with M-Series machines. If anyone knows for sure, I’d appreciate any info.

Brand new Mac Mini, just came out today. It has a full year of warranty left.

It could be a factory defect

Mine so far has had no issues like this. I have one monitor connected straight into the HDMI port and another monitor via a Dell dock (from work).

What is your resolution and refresh rate set to? MacOS can be quite picky.

[-] that_leaflet@lemmy.world 3 points 1 week ago

1440p at 170Hz with the DisplayPort. But I also tried going down to 60hz, but in that brief time I did that, that made the flickering issue even more apparent.

Try 144 or 165 if you have it. It's some sort of matching game rather than hardware compatibility.

My HDMI tops out at 144hz, issue still present.

Thanks for trying. I'm unfortunately out of ideas.
